Hardware Operation
Turning on the unit
Turn the computer on by quickly depressing the yellow on/off button on
the upper right-hand side of the computer (press for ½ to 1 second).
Note: When turning on the machine, DO NOT press the
on/off button twice in rapid succession. A double press
replicates CTRL ALT DEL keystrokes. Holding the on/off
button down for a longer period of time (4-5 seconds)
causes an emergency forced shut down of the computer.
The on/off button is recessed to prevent accidentally turning the unit on
or off. The HAMMERHEAD XRT will perform its self-check routines
during the start-up process. All units are configured at the factory to
automatically boot to the Microsoft Windows Desktop unless a custom
configuration has been requested.
Pen operations
The pen is the primary screen navigation and data entry tool for the
HAMMERHEAD XRT.
Without a keyboard attached, the pen is the
only means of communicating with the computer. Do not lose or
misplace the pen
. The pen is usually tethered to its carrying case.
Attaching the tether to one of the zippers on the carrying case with a split
ring allows the tether to be anchored on either side of the computer. By
shifting the position of the zipper, the tethered pen is convenient for right
or left-handed users. All users are encouraged to purchase a spare pen
as a backup.

The pen functions like a two-button mouse. There are two switches in
the pen, one in the pen tip and another on the barrel of the pen. The tip
switch performs the same functions as the left button on a mouse and
the barrel switch performs like the right mouse button. Very few
applications require the use of the pen’s barrel button.
Do not depress
the barrel switch when writing on the display; it will adversely affect
handwriting recognition
. To activate the tip switch, simply press the tip of
the pen against the display. This is similar to clicking the left button of a
mouse. Double clicking is accomplished by double tapping with the pen.
Move an icon by pressing the pen directly overhead and dragging it to
the desired destination, keeping the pen in constant contact with the
display.
Tapping the pen requires only light to moderate pressure. It is possible
to damage the pen by pounding the tip against the display with force.
Most problems using the pen are related to tapping speed and the
tapping area size. When using XP Tablet PC Edition, attributes related
to use of the pen (e.g. tap speed) can be adjusted by clicking on Control
Panel, Tablet and Pen Settings, and then the Pen Options tab. You can
also improve handwriting recognition accuracy by indicating if you are
right or left handed on the Settings tab. For Windows 98/2000/XP Pro
operating systems, look in the Handwriting directory of the Control Panel.
The HAMMERHEAD XRT utilizes a proximity-sensing electromagnetic
digitizer. This component tells the computer the pen’s exact position.
The computer senses the pen as it nears the display and the cursor
appears when the pen is approximately an inch away. This allows
visibility of the exact location of input before making actual contact with
the display.
The location of the cursor on the display is the location of input
regardless of the location of the pen tip. The cursor and the pen tip
should be closely aligned when the pen is in contact with the display. If
the pen and the cursor are out of alignment, click on Control Panel,
Tablet and Pen Settings and go to the Settings tab where you can
calibrate the screen for both landscape and portrait orientations. If you
are using Windows 98/2000/XP Pro, follow the instructions provided in
the pen directory of the Control Panel. Confirm the display is on the
appropriate setting before attempting to realign the pen.

Touch Operations
Touch Screen Operation
The touch screen replaces a mouse in normal Windows operation.
Wherever you touch the screen with your finger or stylus, the computer
interprets it as a mouse click. Due to the nature of the touch screen, it is
sometimes hard to drag objects across the screen and it is also hard to
move the pointer around the screen without selecting the object below
the cursor. This should be taken into account when applications are
being developed for touch screen devices.
The touch screen unit comes standard with Windows XP Pro, Pen Office
Calligrapher and My-T-Pen on screen keyboard software and therefore
may not offer some of the Tablet PC functionality of a pen unit running
XP Tablet PC Edition such as screen rotation. It is also very difficult to
capture a signature on touch screen units.
Caring for the Touch Screen
With minimal maintenance, the touch screen will last many years. When
operating the touch screen, you should not use an abrasive or metallic
pointer. The touch screen is easily scratched if an abrasive stylus is
used. We recommend using your finger or a plastic tipped stylus. Be
careful not to let sand or grit sit on the screen. Cleaning of the touch
screen can be done with a regular plastic cleaner such as Plexus.

Battery use and care
The Lithium Ion batteries used in your Hammerhead computer offer the
best technology available today. These 'Smart Batteries' provide
Hammerhead users with the greatest power density and the most
accurate gas-gauge possible. To achieve the best possible performance
from your batteries, we recommend using and maintaining the batteries
in accordance with the instructions provided below.
Getting started with your new batteries
Your unit comes with a Lithium Ion battery that is shipped (uninstalled) in
the box with the unit. The unit may also have a non-working battery shell
in the second battery slot that shows you how the battery is to be
installed. Due to current regulations regarding shipment of Lithium Ion
batteries, your battery(s) will arrive in a partially charged condition,
typically with a maximum charge of 30% to 50%.
You need to install
your battery before turning on the unit.
We also recommend that you
fully charge your batteries before using them. If you do not plan to
deploy your computer immediately, please be aware that the batteries
self-discharge at a slow rate, typically less than 10% per month at
normal temperatures.
How to install new batteries
The Hammerhead XRT has the capability to run on one or two batteries
in the field. The unit does not require both batteries to run. The two-
battery design allows users to hot swap batteries without turning the
computer off.
To install or replace a new battery, turn the round knob on the back of
the unit. The knob holds the batteries in place and is designed so the
batteries cannot be taken out at the same time. Simply turn the knob
until the quarter piece exposes the corner of the battery that is to be
replaced. A lip on the battery aids for easy removal. Install the new
battery by placing it into the compartment and turning the knob to cover
the edges of both batteries.
When to recharge batteries
The green LEDs on the upper right front of the unit indicate the power
status of the battery. At full charge, all five LED indicators will light a
